ROLLERSUPPOR-T FOR SLIDING DOORS.

Patented Feb. 2, 19 09. p this application filed. December 24:, 19;

'To all whom -it'may concern: 1

Be it known that I, DE WIT'r-O. EDMOND- SON, a citizen of the United States, residing at Evansville, in the county of Vanderburg and State of Indiana, have. invented certain new and useful Improvements-in Roller-Sn orts for Sliding Doors; and I dodeclare 't e ollowing to be a full, clear, and exact de'-- reference being had e accompanying drawings, and to the letters and figures of reference marked there on, which form a part of this specification.

This invention relates to roller supports for edgewise movable doors.

The objects of the invention are to provide improved appliances for supporting sliding doors, particularly car doors; to provide scripfion of the invention,

roller supports which may be constructed of.

metal that will be least liable to break in use and be adapted to be repaired when damaged, and to provide roller supports that may be relied on to operate freely, and be durable and economical in use.

With the above-mentioned and minor objects in view, the invention consists in roller sup orts for doors of novel construction, and in t e combinations and arrangements of ele ments as hereinafter described and pointed out in the appended claims, said invention having been shown in my application for Letters Patent of the United States, filed April 27, 1906, Serial No. 313,937, this being-a divisional application for Letters Patent for certain features not claimed in said prior application.

Referring to the drawings, Figure 1, is a fragmentary side elevation ofa box-car body having the improvements applied thereto as illustrating the application and functions thereof; Fig. 2, a fragmentary vertical sec tional viewon the line A A in Fig. 1 Fig. 3, a

fragmentary vertical sectional view on the line B B'in Fig. 1; Fig. 4, a fragmentary vertical sectional view showing the lower part of the door and bearing shoe thereof, Fig. 5,

a fragmentary vertical sectional view, as at the line C in Fig. 1 Fig. 6, a fragmentaryvertical longitudinal sectional view of the lower door rail as on the lineD D in Fig. 3; and Fig; 7, a fragmentary vertical sectional view,

as at thelineEinFig. 1. 7

Similar reference characters designate corresponding elements orfeatures'in the various figures of the drawings, parts of the car and doors together with certain of the attachthe guide sideg of the rail F.

ments being herein indicated as being advantageously associated with the present 1nvention.

In the drawings, a, designates a side-sill of thecar body; I), the siding; c,'the carfloor; d, the roof; and e and f, the door-posts at opposite sidesof adoor way of the car, all of ordinaryconstru'ction.

In practical embodiment, the ,inventlon meludes a lower door'rail F whichis composed gland suitably secured against the siding bopposite to the side sill a, the rail beingso formed as to have an inclined guide sideadjacent to the siding at anangleto the, base, a narrow top h, andan outer inclined guide side '8 extending downwardly from the'to h, all integral, so that the'cross-secti on of t e rail resenibles that of the frustumzof a cone. The top it of the rail hasa suitable hurnher of apertures therein in which rollers G are arranged andmounted on axles k that are'supported by the inclined guidesides g and i, the-follers being nearly incasedin the holimv rail with the to s of the rollers slightly above the tops 71 of tie rail. The axles k are held removably in the guide sides 9 and'i by nuts I. An upper guide railH is suitably secured to the side of the car body, the rai having a lip m extending dowmvardly, and a guide platen is interposed, as shown between the siding b and the rail.

The-rails F andH are usually of suitable length so as to accommodate two doors, as shown in Fig. 1, a tight door I and a ventilating'door J. The framing of the doors; may be variously constructed, and each door has a rooved bottom in which is ametal shoe having a guide lip K"ext'endingover the side i of the lower rail while the 95 shoe bears onthe, rollers G. The shoefhas j also; an inner guide lip K extending lover p Also the shoe. is provided with a pair'of. flanges O and P which embrace the door to which they are 100 secured for attaching the shoe'to the door.

The top of each door is provided with a face-plate L thathas a flange g. a

In order-to effectually retain the car doors on the lower rail a pair of substantial stops 105 M and N are secured to the sideof the car body'at the ends of the door rails. The doors have handles 0". The lower rail is secured in the desired position 'by bolts 8.

In practical use, the doors will move 1 10 of rolled inetal to form a base having bolt-holes eesiiy on the rollers and advantageous res suits attained by the ebove-desoribe'd construction wiil be fully understood as being obvious from the detailed desori tion of construction, sufiee it to say t let cost oherges 'for lost oar doors may be avoided by the use in? the invention.

Havin thus described the invention, whet is oieimed es new is- 1. A door reil oomo'rising at base with bolteholes' therein, a at inner. guide side extending from the hose st an obtuse angle,

e, flat to extending at an obtuse angle from the gui e side, and s fist outer guide side extending from the top at on obtuse angle.

2, The ooinbmation with e ear body side,

of e lower door rail comprising e base atteehed to the body side, on inner guide'side extending onward from the base at an obtuse angle thereto and ewe from the body side end having openings tw erein to receive axles, s to extending from the guide side and sway 110111 the ear body side and having apertures therein, an outer guide side extendin fromthe top downward and outward therefrom and having openings therein to receive axles, axles mounted in the openings of the guide sides and extending under said top, end rollers mounted on tne axles having openin s therein to receive axles, a 1

top extending roni the guide side andown from the body side and having apertures therein, an outer guide side extending from the to dovmwrtrd and outward therefrom to guir e the other guide lip of the door and I s.

having openings therein to receive axles, sxles mounted in the openings of the guide sides, and rollers mounted. on the axles between the guide sides and protruding through the apertures of the top to support the door.

in testimony whereof, I ofiix my signature in presence oi two witnesses.
